Fix leak in single-touch.html

This test could trigger leak detection since not waiting on pointerup
after all of the async tests have completed.

Actions().send() does not wait on the dispatched events to be handled.
Each async test marked itself as done once the expected event was
received. Refactored to be a promise driven test.

2 flakes out of 100 runs without the fix.
0 flakes out of 500 runs with the fix.

VT: Deflake nothing captured view transition test.

Instead of relying on a double rAF, use waitForCompositorReady in
an attempt to deflake the test.

Also update the takeScreenshot condition to await the ready
promise instead of a double raf.

DOM: Support disconnected->disconnected moveBefore()

Per discussion in whatwg/dom#1307, we've
decided to support moveBefore() in the disconnected->disconnected
scenario. This CL enables and tests that.

[css-pseudo] Fix marker-text-combine-upright.html

This test was failing for 2 reasons:

1. ::marker had text-align: start and text-align-last: start as
   important UA rules, while the style adjuster only enforces
   text-align: center in the presence of text-combine-upright: all.
   This resulted in text-align: center; text-align-last: start.

   Arguably the style adjuster should also set text-align-last,
   but a smaller fix is changing the important UA rule for ::marker
   to text-align-last: auto. Note text-align-last: auto behaves as
   text-align-last: start when text-align: start, so the change
   has no effect in the great majority of cases.

2. The style adjuster enforces white-space: pre on outside markers,
   even if the test uses all: unset.

   So this changes the test reference to expect white-space: pre,
   and explicitly sets white-space: pre in the test for Firefox.

[@scope] Pass TreeScope separately to SelectorChecker

The scope member of SelectorCheckingContext is currently used
for several closely related (but different) things, causing subtle
bugs and a hard-to-understand model.

To address this, pass the TreeScope to SelectorChecker separately,
and use context.tree_scope for ShadowRoot-dependent decisions
in selector matching.

The context.scope field is now only used for two things:

1. For matching the :scope pseudo-class.
2. For creating the default activation for @scope.

This fixes Issue 377647716, because since we no longer "clobber"
context.scope during scope activation, making ParentElement
traverse to the shadow host.

Make ConsumeNumberOrPercent() not crash on unresolvable calc().

Instead of calling GetDoubleValue() on percentage calc expressions,
we just return them directly, and then add a new rule saying that
ComputeNumber() on them returns the percentage value divided by 100.
This avoids crashes when we try to force them during parsing.

This also takes us halfway towards fixing the opacity-valid.html test;
we no longer convert it into just a double (without surrounding calc()),
but since we don't properly simplify comparison expressions containing
percentages, we don't simplify as much as we should either, so the test
is still broken. (And even after that, we'd probably need to convert
percentages to decimals inside calc for such properties.)
